IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of vLetters Patent No. 196,690, dated October 30, 1877; application filed June 23, 1877.

To all whom 'it may concern:

Be it known that I, ENos MEAD, of Dexter, in the county of Dallas and State of Iowa, have invented anImproved Sash-Holding Device, of which the following is a specification:

The object of my invention is to provide a simple device that can be readily applied and operated to hold a movable window in its frame at any point desired.

It consists in the novel method of arranging and combining, as a permanent xture in a window-frame, a shaft having a knob on its outside end, an eccentric, and4 a spring friction-plate, all 'as hereinafter more fully described and claimed.

Figure l of the drawings is a side elevation of a window, having` my ixture applied to illustrate the construction and operation of my complete invention.

a a represent a mortise and cavity in the window-frame. b is a horizontal shaft that has its bearings formed in or attached to the window-frame acings( c is a knob on the outside end of the revolving shaft b. d is an eccentric rigidly flxed on the central portion of the shaft b, by means of a screw or in any suitable way. g represents a flexible or spring friction-plate, preferably steel, fastened at its top end, immediately over the mortise a, in such a manner that it will extend downward over the mortise, and close it, and conceal the eccentric d. h represents the movable sash of a window designed to be alternately raised and lowered 'in the grooves formed by the vertical windowstops.

Fig. 2 is a perspective view, showing the fixture, and the eccentric turned to press the lower and free end of the spring friction-plate g outward, as required, to engage and hold the movable window.

Fig. 3 is a modiied form of an eccentric, d',

designed to be turned only one way to engage the spring friction-plate g.

In the practical operation of my invention, when the eccentric does not press against the friction-plate, the window is free to be raised or lowered, as desired, and in order to hold and lock the window in a closed or opened position, I simply, by means of the knob on the outside end of the'shaft, turn the eccentric to engage the spring friction-plate, and press it against the face of the window -sash. rIhe friction thus produced between the faces of the spring friction-plate and the sash will lock them together, and retain the sash in a iixed position. To release the sash I simply turn the knob and the eccentric in a reverse way.

I am aware that cams and eccentrics have been fixed 011 handles to engage window-sashes direct, and to also press strut-springs against the sliding sashes to hold them by friction at any point desired.

I am also aware that a spring has been fixed at one end only to be operated as a sash-holder by means of a screw; but my manner of xing a spring friction-plate to a window-frame at one of its ends only, and operating its free end and body by means of an eccentric carried on a revolving handle to hold and lock a movable sash at any point desired by friction, is a simple, novel, and advantageous arrangement and combination of common mechanical dcvices.

I claim as my invention- As an improved sash-holding device, the revolving handle b c, having a iixed eccentric, d, in combination with the spring friction-plate g, rigidly secured to the window-jamb at one end only, to operate against a4 sliding sash, h, substantially as and for the pmposes shown and described.
